Dental anxiety, cardiovascular changes and patient preconceptions toward implants and root canal treatments: An observational study.

Background: There is little information about dental anxiety and the patient's vital signs during dental procedures. This study evaluates and compare patient anxiety levels and cardiovascular changes before and during root canal treatment (RCT) and single-tooth implant procedures.

Material And Methods: Preoperative data and pre-treatment considerations were recorded.

In vitro assessment of PEEK and titanium implant abutments: Screw loosening and microleakage evaluations under dynamic mechanical testing.

Statement Of Problem: Polyetheretherketone (PEEK) has been advocated to replace metal components in dentistry. Although PEEK is a high-performance polymer with a white color, adequate biological response, and resistance to fracture, data to support PEEK as an alternative material for implant abutments are lacking.

Purpose: The purpose of this in vitro study was to assess the mechanical and functional properties of PEEK implant abutments as a nonmetallic alternative to titanium abutments, which presents esthetic limitations and greater difficulty to customize clinically.

Dental Anxiety, Fear, and Root Canal Treatment Monitoring of Heart Rate and Oxygen Saturation in Patients Treated during the Coronavirus Disease 2019 Pandemic: An Observational Clinical Study.

Introduction: The present study aimed to evaluate anxiety in patients and to monitor their heart rate (HR) and blood oxygenation (SpO) before, during, and after a root canal treatment (RCT) during the state of alarm in 2 different periods of strict and partial confinement.

Methods: The patients who required a primary RCT were selected. Demographic, preoperative, and postoperative variables were registered, including perceived dental anxiety, fear, HR, and SpO.

General Anxiety in Dental Staff and Hemodynamic Changes over Endodontists' Workday during the Coronavirus Disease 2019 Pandemic: A Prospective Longitudinal Study.

Introduction: The aim of this study was to assess general anxiety levels in endodontists and dental assistants related to different conditions during the pandemic and lockdown and to evaluate hemodynamic changes in endodontists' heart rate (HR), blood pressure, and blood oxygenation during their workday.

Methods: Anxiety levels in endodontists and dental assistants were recorded weekly during the state of alarm declared because of the coronavirus disease 2019 pandemic. Hemodynamic parameters were monitored using a sphygmomanometer for HR and blood pressure and a pulse oximeter for oxygen saturation.
